I can't tell anyone about this. Although it happened almost affected my entire life, I must also firmly keep this secret forever, at least in reality. Fortunately, there is this online world that can face people who don't know each other casually. Since childhood, my cousin and I have deep sisterhood. My sister is five years older than me. In my eyes, she has always been a perfect girl. My family lives in a rural area in the suburbs. I am really a girl who grew up in the countryside. But I have seen the world and yearn for life in big cities since I was a child. My sister grew up in the city and was born and raised in Beijing.
